Description

Technical Field

[0001] The utility model relates to the technical field of wire-laying pulleys, in particular to a wire-laying pulley with a braking function. Background Art

[0002] The cable-laying pulley is mainly used to protect the cable conductors when they are laid. When laying power cables, cable-laying pulleys are often used to prevent possible wear on the cable surface due to friction between the cable and the ground, friction between the cable and the building corners (such as wellheads, cable trench corners, etc.) when the direction changes, friction between the cable and the pipe openings when the cable passes through multiple parallel cable ducts in sequence, and friction between the cable and the pipe openings when the cable passes through two cable ducts at angles to each other in sequence.

[0003] According to the description of the wire-releasing pulley with brake function disclosed on the patent website (authorization announcement number: CN 219268325U), "The utility model discloses a wire-releasing pulley with brake function, which relates to the technical field of wire-releasing pulleys, including a mounting base, two lower fixed plates are fixedly connected to the upper surface of the mounting base, an upper movable plate is slidably mounted on the side wall of the lower fixed plate, a wire-releasing roller is rotatably mounted between the two upper movable plates, and the same U-shaped plate is slidably mounted between the tops of the two upper movable plates, and a movable mounting rod is penetrated and slidably mounted on the top of the U-shaped plate. The utility model cooperates with the wire-releasing roller, the U-shaped plate, the movable mounting rod, the brake hammer, the swing rod, the mounting vertical rod and the reset tension spring. When one end of the swing rod is tilted, the other end can drive the movable mounting rod and the brake hammer to move downward until the brake hammer presses the cable on the wire-releasing roller. At this time, the cable can stop releasing the wire to achieve the braking effect. In this way, the length of the cable release can be timely controlled during the cable laying process, which is more conducive to the cable laying work."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, the brake hammer is moved downward until the brake hammer presses the cable on the wire-releasing roller, at which time the cable can stop releasing the wire and a braking effect is achieved.
